Benefits of technology

The patent allows for adjusting parts of a car that help it move smoothly based on information from sensors that detect potential obstacles it might hit while driving.

Problems solved by technology

As an automotive vehicle travels, it disturbs the air through which it passes.
This air disturbance has an impact on energy consumption of the automotive vehicle, among other factors.
The greater the wind resistance and turbulence, the greater the expenditure of fuel and the lower the fuel economy.

Abstract

In an exemplary embodiment, a method for controlling a vehicle includes the steps of receiving, by a vehicle controller, sensor data representing a vehicle environment along a projected path of travel of the vehicle from at least one sensor, determining, by the vehicle controller, if the projected path of travel of the vehicle includes an obstacle, determining, by the vehicle controller, if an underbody component of the vehicle will impact the obstacle, and if the underbody component will impact the obstacle, generating, by the vehicle controller, a control signal to move the underbody component from a first position to a second position.

Description

INTRODUCTION[0001]The present invention relates generally to the field of vehicles and, more specifically, to aerodynamic features of automotive vehicles.[0002]As an automotive vehicle travels, it disturbs the air through which it passes. This air disturbance has an impact on energy consumption of the automotive vehicle, among other factors. Overcoming wind resistance and turbulence generated by the passage of the vehicle expends energy, which must be obtained from fuel, electricity, or other stored energy of the vehicle. The greater the wind resistance and turbulence, the greater the expenditure of fuel and the lower the fuel economy. Vehicles are therefore generally designed with aerodynamic performance in mind. In conventional vehicle design aerodynamic features were generally fixed body structures on the exterior of the vehicle. However, recently, actively movable aerodynamic features have been implemented on some vehicles.SUMMARY[0003]Embodiments according to the present disclo...
